' Letters Patent No. 62,573, dated March 5, 1867;

IMPROVIID WASHING MACHINE.

TO ALL WHOM IT MAY CONCERN:

-Be it ltnown that I, JAMES TiIOMPsON, of Vevay, Switzerland county, Indiana, have invented a new and useful Washing Machine; and I do hereby declare the following to be `a full, clear, and exact description thereof, reference beinghad to the accompanying drawing, the same being a transverse section.

This invention relates to an arrangement of parts whereby a treadle worked by the foot of the operator is made available as the principal motor, while a yielding pressure-board, under controlof either hand, enable. the optional increase or decrease of the rubbing stress upon the vclothes.

A' is a trough-like box or tub, formed by two vertical ends, a, two sloping sides, a', and a flat bottom, a. The shaft b ofthe roller B is journalled in notches, C, in the ends o f the tub, and is provided outside ofthe tub with two fly-arms, D, haviing pit-men, E, which connect said arms with atreadle, F, hinged to the frame G, which supports the tub.. H is thepressure-board, pivoted at I within the tub, and caused to press upward against the roller B. either by loading its handlei, or by the provision of an upward bearing spring, K, or both.

The periphery of the roller B may be armed with alternate wooden and metallic ridges, L M, or may have any desired ribbed or corrugated form. The sides ot' the pressure-board frame slope downward at N to support tho journals of a loose roller, O. i

Operation: rIhe box being half illed'with suds, the clothes are placed in the space between the roller B `and the side of the tub most distant from the operator. The ti'eadle being then set in motion, the roller B is thereby rotated in direction of the arrow, so as to catch and draw fornard'the clothes between the 'rollers B and O above and thepressure-boardA below' them, to which board the left hand of the operator may. impart more or less stress at discretion. vThe iy-arms'may be so weight-ed as to counterbalance the gravityrof the treadle and pitnien. .Both rollers B and O are free to risc and fall with greater or less hulk of clothes, und both 'are capable of unshipment when required. The fly-arms and their appendages serve the twofold purpose of ayielding pressure and a sustained momentum.

I claim herein 'as new, and of my invention rlhe combination ofthe yielding rollers B O, ily-arms D, treadle'F, and controllable pressure-board H, all constructed and arranged to operate as and for the purposes setl forth.

In testimony of which invention I hereunto set my hand.
